Working Principle

Once the product is fed into the manhole to the desired capacity, clamps seal the cover and rotation begins. As the CDB revolves, the top layer of the product rolls down toward the opposite cone and is followed by the entire mass. The conical walls deflect the product toward the center producing a constantly changing cross section of material that blends as it dries. The jacket surrounding the vessel contains a heating medium that is circulated by means of a rotary joint or through the center of the support shaft. A vacuum tube removes vapors formed by the heated jacket.
◎Let heat source(for example,low pressure steam or thermal oil)pass through the sealed Jacket The heat will be transmitted to raw material to be dried through inner shell;
◎Under driving of power,the tank is rotated slowly and the raw material inside it is mixed continuously.The purpose of reinforced drying can be realized;
◎The raw mate rial is under vacuum The drop of steam pressure makes the moisture(solvent)at the surface of raw material become saturation and will evaporate The solvent will be discharged th rough vacuum pump and recovered in time The inner moisture(solvent)of raw material will infiltrate,evaporate and discharge continuously The th ree processes are carried out unceasingly and the purpose of drying can be realized within a shon time.

Material to Be Dried

It is suitable for the raw materials that need to concentrate,mixed and dried at low temperature(for example,biochemistry)products in chemical,phamaceutical and foodstuff industries.Particularly it is suitable for the raw materials that are easy to be oxidized,volatilized and have night heat sensitivity and is toxic and not permitted to destroy its crystal in drying process.

Characteristics
◎When oil is used to heat,use automatic constant temperature control.It can be used for drying biology products and mine Its temperatu re of operation can be adjusted form 20-160oC.
◎Compared to ordinal d ryer,its heat efficiency will be 2 times higher.
◎The heat is indirect So the raw material can not be polluted.
◎It is in conformity with the requi rement of GMR It is easy in washing and maintenance.
